Abstract

858,198. Combined magnetic/optical soundon-film apparatus. KODAK Ltd. July 3, 1958 [July 3, 1957], No. 21361/58. Class 40 (2). A kinematograph projector having a sound drum 6 and associated optical apparatus 8, 9 of normal construction has a magnetic transducing head 15 mounted to engage a magnetic stripe on the film, simultaneously or optionally with the optical apparatus. The head is mounted by a stalk 28 in the arrangement of Fig. 4, which provides adjustments to align the head with the film and which includes a spring link 31 to force the head against it. A lever 35 moves the head out of engagement, a mechanically-linked micro-switch 38 revising the circuitry (not described) for use with optical sound-films.
